' Application lllcd August 18, 1911. Serial No. 644,829.

: To all whom it mo concern:

.. Be it known that I, FRANCIS J. One, a

i citizen of the United States, and aresident of Buffalo, in the county of Erie and State 3 act description.

of New York, have invented a new and Im proved Furnace for Gas-Generators, of which the following Isa full, clear, and exapplication relates to imfurnaces for heating extegenerators disclosed in an The present provements in riorly the gas application for patent for improven'ients in system and apparatus for generating and burning oil gas, filed by me Aughst 5, 1909,

and bearing No. 511,291, which application was renewed June 30,1911, bearing Serial ;No.' 636,293, to which application cross refl erence is here made;

The present invention has for its principal ob ects to conserve the maximum units of heat by heating the walls and interior j structure of the furnace to a radiatingcondition, wl1ich, after being raised to the necessary temperature, is theremaintainerl by renewing t e heat lost by radiation; and to provide a simplified form of conveyance rOIXtI'RIISfEI of air and gas through the walls and structure of the a maximum eft'ect.

furnace to produce the v One embodiment of the present invention Qis'disclosed in the structure illustrated in the accompanying-drawings, in which like *wcharacters of reference denote correspondin" parts in all the views, and in which i lgure 1 1s a vertical section of a furnace taken on one of the diameters thereof; Fig.

. 2'is a cross section of the furnace taken on the line 2+2 in Fig. 1'; Fig. 3 is a vertical section taken on the line 3-.-3 in Fig. 4;

Fig. 4 is a cross section on diminished scale, the section being taken on the line 4+4 m Fig. 1; Fig; 5 is a cross section on diminl ished scale, the section. being. taken on the line 5-5 in Fig. 1; and Flg. 6 is a side view section thereo showing a fra ent. of the furnace and'a taken-on the line 6-6 in Fig. 4.

The construction and operatlonof the generator A is shown and described in the application for patent above referred to.

i It is found expedient and advantageous to whereof arc.cm1cavcd to form the round dome above the body of the chamber 1]. The blocks 1;! are prcl' rably four in number-and arc hcldin position by being bound by the strap 13. The side walls of the furnace are mounted and built upon the bottom tiles 14, which may be of lire brick. or other refractory material, and are preferably four in number and are so-shapcd as to form, at the center of the furnace, an opening 15. The opening 15 communicates with, a laterally opening passage 16. The tiles ll rest upon the 'l'oundution 19 in which the passage 16 is formed. The foundation 1!) rests upon the blocks 1'7,'17-and 18. Between the blocks 17 and the central block 18 are formed the transverse passages 20, 20. The passages 20, 20 are in open connnunication with-tho vertical passages 21. .The vertical passages 21 are l'ormcd between the side walls 22 and the inner walls 23 of the hollow metal jacket with which the furnace is provided. V

The hollow metal jacket is provided with the inner wall and the outer wall 24, and

is formed as an open box havingverlical sides and a horizontally .cxtended bottom. At the upper edge the walls 2 3 and 24 are capped by a closure edge 25. ()pening into the hollow metal jacket, and n'cfcrubly at.

the center of the bottom thereof, is a supply pipe 26. 5

The passages 21 a re closed by the vertical walls 27 which are disposed in a plane perpendicular to the extension of the passages 20 and divide the passages 21 into two pas sages con'nnunicaling on the one side with the delivery fiuc2a'. 'lhc passages 21 are terminated at the upper end by the extension of the side wall blocks 29. The blocks 29 are extended to abut the inner walls 23 of the metal jacket. The blocks 29 are'suitably provided with inlet passages 30which, through registering perforations formed in the ilincr wall .23 of the jacket form an opening connminicating with the hollow space of thesaid jachct.

The pipe 26 isoscd to supply fresh am the oxygen whereof is substantially burned in the chamber 11 ofthc furnace. This air is delivered through the pipe 26 and spread laterally between the walls 23 and 24. and

is imrraluccd into the chamlmr through the passages 30 where it supplies the necessary oxygen for sustaining combustion.

The passage 16 is utilized for ll'ltIOdllC:

out in said application.

'10. throu h the'passage ing preliminarily the b\1'i*ning* gaswhicl1 is delivered from a torch 31, said torch being constructed and arranged substantially as disclosed in the application above referred to. Suilice for the present instance to say that the torch is provided to deliver air or steam while the pipe 32 delivers oil under pressure and under conditions as pointed The torch 31 in delivers the flame. thereof 16 against the farthest by the foundation 19.

its I operation,

are introduced into the chamber 11 at their the oxygen highest temperatures to immediately absorb fromthe' air introduced through the passage 30 to form'a superheated medium capable of sustaining chemical com-v bustion. v

After the furnace has been thoroughly rimed, if so desired, the employment 0 the torch 31 ma be discontinued,.and the passage 16 is t en closed or blocked. As dcscribed in the above cross-reference appliber 11,

by a suita le valve.

cation the walls of the generator A are per- .foratedto supply a certain proportion of the gas generated therein directly outward into the furnace. Under ordinary pressure this supply of gas is not sufficient to sustain the necessary combustion within the charm the additional gas required being supplied b the pipe 33 which is controlled When the device is running at full capac ity, and hence under greater ressure, more gas is forced through the said openings in the generator, and the pipe 33 may be shut off, more or less, by the valve. Thus heat of the generator may be kept at the desired point. This extragas forced through the small openings is burned by forcing more air into chamber 11, or, allowed to pass unburned up'the flue 28. Passing oif the gas unburned is rendered unnecessary byproviding the requisite number of small openings. Extra air for combustion purposes within the chamber 26, control of which is obtained by means of I a suitable valve.

After the necessary startin heat has been supplied and the walls of t have been thoroughly heated, the operation of the furnace is automatic. The greater the heat produced in the, furnace the larger the quantity of gas admitted through the generator. The heat of the furnace is regulatedand controlled in a large measure by the farther end of the 11 is obtained by pipe e chamber'ill -to the flue 28 by the amount of air-supplied through the pipe 26 and hollow jacket surrounding the furnace.

In the operation of the furnace combusted gas and air are led through passages formed about the pipes A, A A and 33', through the wall 22 and into the passage 21' at the one side of the walls 27.' In the passages 21 at the inner side of the Walls 27 the air is carried down to the passagesfll) which pass. under the foundation 19 and communicate with the passages 21 on the-opposite side of the furnace. The burned gas arises through the passage 21 on the far side of the furnace and enters the delivery flue 28.

It will be seen that the passages 21, 20, 21 are so situated walls of the furnace, mit in the passage from radiation the maximum units of neat carried by the escaping burned air and gas. It will also be observed that by reason of the distribution of the passages 21 adjacent the inner jacket the incoming air is pro-heated for de-" livery within the said chamber.

Haviii what-I c aim as new and desire to secure by Letters Patent is 1. A furnace of the character described,
